Top definition
A woman who is too much of a mess (physically and/or emotionally) to be worthy of being called a "bitch."
That hypocrite likes to pick apart everyone else's flaws which she also has but won't accept. What a cankletwat!

"Cankletwat" can also be used as a term of endearment between very close girlfriends, as in, "No more martinis for you, you sassy cankletwat."
